Cyber
Monday is the monday following
Black Friday. From Wikipedia, the free
encyclopedia:

The term Cyber
Monday
refers to the Monday immediately following
Black Friday, the ceremonial kick-off of the
holiday online shopping
season in the United States between Thanksgiving
Day and Christmas. [1]
Whereas Black Friday is associated with
traditional brick-and-mortar
stores, "Cyber Monday" symbolizes a busy day for
online retailers. The
premise was that consumers would return to their
offices after the
Black Friday weekend, making purchases online that
they were not able
to make in stores. Although that idea has not
survived the test of
time, Cyber Monday has evolved into a significant
marketing event,
sponsored by the National Retail Federation's
Shop.org division, in
which online retailers offer low prices and
promotions.

:Black Friday
is
the day after Thanksgiving. Black refers to ink color.
Most retailers
don't show a profit for the year until this day after
Thanksgiving. It
is also a time for great bargains.
